Today I have added a hack to Plasma NM to make the traffic graph work with ppp connections. The problem was that NetworkManager only provides the serial device name (e.g. /dev/ttyACM0 or /dev/ttyUSB0) and Plasma::DataEngine expects the network interface name (ppp0) used by the device. I hacked Plasma NM by changing the Plasma::DataEngine::connectSource parameter to always use ppp0 when the interface name contains ttyACM or ttyUSB. I know that is ugly and error prone, if anyone knows how to convert serial device names to network interface names let me know. The only way to do it I have found so far is monitoring /var/log/daemon (or /var/log/messages) for the line pppd[
]: Connect: ppp0 <--> /dev/ttyACM0, but that is also ugly and the log file containing the needed information can be different on each platform KDE SC is installed.
I have also tested Plasma NM with my Samsung i8910 cell phone. It only connects if I set Plasma NM's tray icon -> Manage Connections -> Mobile Broadband ->
-> Edit -> Type to "Any" (it was "Prefer3G" before the change). Maybe someone else also needs to change that to make his/her phone connect. The number to dial also needs to be *99# instead of *99***1# . That is strange because my Sony MD300 modem works with *99***1# and as far as I know *99# is a short name for *99***1#.
Modem Manager does not report the access technology (Edge, HSDPA, etc) for my cell phone. I have received the report that Nokia N95 also connects and MM also does not report the access technology for that phone too.
There are other changes I am working on, when they are ready I will let you know :-)
